1 Claim.

This invention is-directed to the provision of portable air conditioningequipment which is very efflcient in operation, compact and simple inconstruction and relatively inexpensive in operation.

The accompanying drawing shows an embodiment of the invention in partsectional elevation.

Referring to the drawing in detail, I designates an enclosing cabinetdivided by transverse partitions 2 and 3 into an air conditioningchamber 4, a motor and condenser chamber 5 and a compressor chamber 6.

The air conditioning chamber 4' is provided with air intake grilles- 1formed in the walls of. the cabinet I and with a discharge throat andair discharge grilles 8 and 9 at the top of the cabinet. e

Within the air conditioning chamber I provide a set of coiled airconditioning tubes 10, air being drawn into the chamber 4 through thegrilles i and over and around the conditioning coils or pipes ill by afan It disposed at the mouth of the throat 8, the air being dischargedby the fan through this throat and discharge grilles 9 to the room orenclosure in which the cabinet is located. The fan II is driven by avertically disposed motor l2 which is within the conditioning chamber 4and mounted on springs IS on the upper face of the partition 2.

In the lower chamber 6 o! the cabinet is the compressor It, thecompressor being supported on spring mounted frame l5, which extendsinto the intermediate chamber 5 where it supports an electric motor l6.g

The compressor I l and motor l6 are mountedvertically and in alignmentwith each other.

In the chamber 5 and surrounding the motor i6 is an air cooled condenserH. The upper end of this condenser is connected by tubing I8 to a tankI9 which is connected by tubing 20 to the discharge side of thecompressor Hi. The otherend of the condenser is connected by tubing 2|to a tank 22. The tanks l9 and 22 are disposed in the chamber 6 of thecabinet I.

The conditioning fluid which is compressed by the compressor I4 isforced through the condenser and liquefied, the liquid passing into thetank 22 from which it is forced by the pressure in the system throughthe tubing 23 which extends from the interior of the tank 22 near thebottom thereof upwardly through the cabinet to the intake end of theconditioning coils III in the chamber 4. The tubing 23 is provided withan expansion valve" 24. The conditioning fluid after circulating throughthe conditioning coils I!) returns to the intake side of the compressorby tubconduit 26, the outer end of which may be placed in position in awindow opening, for example, and

air is drawn through this conduit into the lower chamber 6 of thecabinet I by a fan 2'? which is mounted on the drive shaft 28 whichconnects the compressor It and motor iii. The air which is drawn intothe cabinet by this fan is discharged out of the cabinet after passingover the coils of the condenser ll throughconduit 29.

The above described device is very simple and inexpensive inconstruction, the vertical mounting of the compressor I 4, its drivemotor l6 and the. vertical mounting of the separately controlled motor Hwhich drives the air fan It conserving floorspace as will beappreciated. It will be appreciated also that by driving the fan II withits own motor l2 the air in which the device is located may becirculated without the necessity of running thecompressor It.

It will be appreciated, furthermore, that by providing the fan H withits individual motor I 2 the apparatus can be operated at considerablesavingin current consumption as compared with apparatus wherein wheneverit is desired to run the fan H when it may not be necessary to run thecompressor it both fan and compressor are necessarily driven due to thefact that one motor is employed for driving both.

It is to be understood that changes may be made in the details ofconstruction and arrangement of parts hereinabove described andillustrated in the accompanying drawing without departing from thespirit and scope of my invention.

What I claim is:

Air conditioning equipment comprising in combination an enclosing casingprovided at its upper end with an air conditioning chamber, airconditioning coils in said chamber, an electric motor verticallydisposed in said chamber, a fan in said chamber driven by said motor fordrawing air into said chamber and discharging it therefrom, a compressofla motor for driving the same and a condenser insaid casing below saidchamber, said compressor and motor being vertically disposed and invertical alignment with each other and with said first mentioned motorand fan, said condenser being connected to said conditioning coils,operation of both motors effecting circulation of conditioning fluidthrough said coils and the passage of air into the conditioning chamberabout said coils and the discharge of conditioned air to the exterior ofsaid casing, the first mentioned motor being operable individually toeflect air circulation without conditioning.
